I'd like you to know that a lot of us read and appreciate your posts, Romstar. Without them, we'd lose so many opportunities for flaming people who didn't search before posting.
Just as an example (please don't take it personally coolman, but you're running around in front of the muzzle):
To impression and make a key in this case, you put a nail into a concrete wall, hang your key from it and hit it with your forehead as hard as you can. This gives you the impression. And when you now fill molten steel into this impression, you've got yourself a key. It needs a bit of filing but it's a good start.
For everything else, either use the freaking search engine or hand over the molten steel AND RUN!
It's not the tools that open the lock. It's me.
